OUR FILTRATION SOLUTION.

Seawater treatment solutions

Our seawater filtration solutions help seawater users successfully cope with their challenges and save resources.

Seawater is used in many applications, from industrial water filtration to drinking water solutions. As it contains high levels of chloride, materials that come in contact with seawater must have high chemical resistance, such as polymers or special alloys. Seawater also has a high organic and mineral content and seawater filters must be used to protect downstream systems such as heat exchangers in cooling systems or membranes in desalination systems.

Here are some of the benefits of seawater filtration:

Reduces maintenance, labor and part replacement
Increases reliability of equipment downstream of our filters
Requires less chemical use
Improves water quality
Improves site efficiency
Causes less environmental impact
Saves energy

Our wide range of reliable seawater filters for seawater successfully cope with the challenges of high organic and inorganic matter and are chemical-resistant, as needed in seawater applications requiring seawater treatment systems.

FAQs

What are the common applications of seawater filtration systems?

The most common uses for seawater filtration systems are the protection of MF, UF, NF, and RO membranes, cooling water filtration, offshore filtration: injection water and produced water filtration.

Why is seawater filtration necessary for various industries?

Seawater has a high organic and mineral content and in industries that utilize seawater, it must be filtered to protect downstream systems such as heat exchangers in cooling systems or membranes in desalination systems.

Applications

Top Seawater Filtration Applications

MF / UF Protection

Effective prefiltration is essential to protecting and improving the integrity of membranes and maximizing their performance. Our seawater filtration solutions for membrane pre-filtration applications reduce the particle load, especially those that can cause mechanical damage, save flushing water, energy and chemical use, and provide increased membrane reliability and lifespan.

MF / UF Protection

NF / RO Protection

Fine filtration is required by membrane manufacturers as a pre-treatment process to prevent clogging and physical damage to the membrane surface and layers, and to reduce the formation of biofilm. Our seawater filtration solutions for fine membrane pre-filtration reduce chemical use, lower energy costs and save on membrane replacement.

NF / RO Protection

Cooling Water

Power generation plants and large production facilities typically require a large quantity of cooling water and thus are often located near the sea. This cooling water is used for once-through cooling to lower the temperature of turbines and other equipment. Seawater filtration is often required at the intake to protect the process, and at the discharge point in order to follow strict environmental regulations. Our filtration solutions for seawater are cost effective and successfully handle the challenges of seawater filtration and ensure stable and reliable processes.

Cooling Water

Offshore Filtration: Injection Water

In the oil industry, water injection is where water is injected into the oil field to increase pressure and production, and to improve oil recovery rates. Produced water, contaminated with hydrocarbons and solids, is often used as injection water. Seawater is a source for offshore production facilities and intake is placed at a sufficient depth to reduce the concentration of algae. Both the produced water and the seawater require filtration in order to protect the wells. Our wide range of filtration solutions help to keep offshore injection systems functioning reliably and efficiently.

Offshore Filtration: Injection Water

Produced Water

Produced water is associated with the production of oil and/or natural gas from wells and may also include water produced from reservoirs or injected into wellbores to improve hydrocarbon recovery. Strict environmental regulations require produced water to be recovered and reused, and filtration is needed. Our robust filtration solutions, with a wide range of filtration degrees and technologies, can successfully handle produced water challenges such as high TSS and flow rates.
